Weighing Accessory

For modern Class, John Deere S-series, and Case IH Axial-Flow combines, 3,000 engine hours is low, 3,000–6,000 is mid-life, and 6,000+ is high. Threshing hours (separate counter) matter even more: under 2,500 threshing hours is considered fresh, over 5,000 typically requires concave, rotor, and sieve inspection. Machines from Western European farms often have lower threshing-to-engine hour ratios because they travel more between smaller fields.
